SPINNING .AND TWISTING MACHINE lBEAlM.

Application led J'uly 6, 1327, Seriall No. 203,853, and in Germany July 12, 1926.

, This invention is concerned with an improved bearing of the driving shafts of spin ning, twisting and the like machinery having l worm gear actuated spindles. In my co-pending application Serial No. 38,893 of June 1925, I have disclosed a bearing structure forA this typeof machinery at which the beam sections are centered and aligned by the shaft supporting ball or roller bearings seated directly within the beam section castings and at which the. beam sections are held together by special screws. These screws are however not readily accessible on account of the narrowness of the bearing beam and are frequently the cause of any kind of inconveniences, when the beam sections are assembled.

My present invention tends to do away i with these drawbacks and provides for this purpose a two-sectional casing for the ball or roller bearings, the sections of the said casing having a screw threaded enga-gement and constituting a mechanism for centering and aligning the beam sections when the casing sections are drawn together. The relative rotation of the beam sections can with this improved construction be prevented by the usual stop pins.

In the drawing illustrating two embodiment of my invention Fig. 1 is a transverse section of a sectional bearing beam showing the ball bearings at the interconnection of the beam sections.

F ig. 2 is a section of a roller bearing connection,

Fig. 3 is a section of a ball bearing connection having two rows of balls.

According to Fig. 1 the bearing beam is subdivided into a plurality of beam sections 20 carrying the spindles 21. The spindles 2l are actuated byy worm gears 22 carried on the actuating shaft 23 and having a friction clutch connection` 24 therewith. rlhe beam sections 20 are provided with end walls 2% and 4 lwith which they mutually Contact.

According to Fig. 2 the shaft 3 is supported in and by the end walls 3 and 4 by means of roller bearings 1, not however imn'iediately but by means of an annular casing 2 having itself a tight fit with the bore of the end walls 3 and 4. For holding the roller bearing 1 within the annular casing 2 I arrange a screw cap 5 engaging the end wall 4 with its marginal or peripheral portion 6. I arrange between the inner face of cap 5 and the roller bea-ring a small clearance so that by the tightening of the cap 5 on the casing `the end walls 3 and 4 are pressed uponv each other without the roller Vbearing being clamped orjammed however. Y

' l/Yith this embodiment the casing 2 must project .with its thread portion 12 over the end wall 4 in vorder that the capmay be screwed on. This construction accordingly vwhich the screw thread 11 is arranged. VBy

these guide surfaces 9 and 10 the capris eX# actly held in corresponding guide surfaces of thek rcasing 2tL so thatvit is exactly centered within the casing 2a in independence from the screw thread 11. The cap 8 again bears with its rim 6Fl against the wall 4 so that the casing 2et and the cap 8 may again be used for the contraction of the bearing beam sections as in the case of the embodiment Fig. 2.

I claim:

1. A beam for machines of the character described comprising a plurality of beam scctions having a face to face contact, a Vshaft extending through the said beam sections and having a .support at the joints thereof, worm gears on the said sha-ft for the actuationof spindles, bearings adapted to center and align the said beam sections and intermediate members between the said bearings and the end walls of their coordinated beam sc ctions and constituting means for drawingl adjacent beam sections together.

2. beam for machines of the character described,comprising a. plurality of beam a sections having a face to face contact, a spin# dle actuating shaft extending through the saidbeam sections7 bearings for the said. .shaft arranged within the adjoining end walls of either pair of adjacent beam sections, and annular' casings between the said bearings andthe end walls of their coordinated beam sections adapted to center and align the beam sections and constituting means for drawing adjacent beam sections together.

8. A beam for machines of the character' described comprising a plurality of beam sec` actuating shaft extending through the said beam Ysections and comprising a plurality of shaft sections arranged Within the Abeam :seetions, bearings 'for the ysai-d sli-att arranged Within the adjoining end Walls of adjacent beam sections, annular easings between the said bearings and the end Walls of their coordinated. beam sections for centering and aligning; the beam sections and shaft sections and constituting means 'or drawing adj acent beam sections together, coupling members Carried by the said bearing intermediate the individual shaft sect-ions and adapted to uni-te them into one continuous and aligned vshating and means for locking the lshaft see` tions and Coupling members in their coupling position.

4.' A beam 'for machines lof the VCharacter Vdescribed comprising 4a plurality of beam seetrons rhaving a face to faoecontact, a spindle actua-ting .shaft extending. through the said Vsections lor centering and aligning the Same,

comprising two Aannular m-emb'ershavmg a threaded engagement with each other and both bearing against 'the end Walis fof adi jommg beam sections and eeiistituti-ngmeans for securing -a aee to faceeontaet thereof.

ln testimony whereof Ilatx my lsig a'ture.
